Microwave seminar | 16 April 2026

This lecture will provide a brief introduction to disturbance observer evolution, then how the high-order version is derived and applied. After that, we present several problems in which the disturbance observer proves useful. All the designs, simulations, and experimental results are also provided and analyzed.

Ton Duc Do received the B.S. and M.S. degrees from Hanoi University of Science and Technology, Hanoi, Vietnam, in 2007 and 2009, respectively, and the Ph.D. degree from Dongguk University, Seoul, Korea, in 2014, all in Electrical Engineering. After that, he was a postdoctoral researcher at Dongguk University and a senior researcher at Gyeongsang National University, Korea. Since September 2015, he has been with the Department of Robotics and Mechatronics at Nazarbayev University, Kazakhstan, where he started as an assistant professor, was promoted to associate professor, and was recently promoted to full professor. His research interests include control engineering, electric drives, renewable energy conversion systems, and nanorobots.

He has been an Associate Editor of IEEE Access from April 2017 to August 2024 and of IEEE Robotics and Automation Letters since August 2023. He has been promoted to Senior Editor of IEEE Access since May 2024. He has also been a Guest Editor for special issues of several journals, such as Mathematical Problems in Engineering, Electronics, Energies, and Sensors, Fractals & Fractional, and International Journal of Advanced Robotic Systems. He received the Best Research Award from Dongguk University in 2014, the Most Cited Paper Award from Wind Energy in 2020-2021, and the Outstanding Associate Editor Award of IEEE Access in 2021, 2022, and 2023. He has been listed in the top 2% of scientists based on the citations in the single-year table from 2019 to now, and the career-wide table from 2021 to now. In 2024, he received the Medal from Kazakhstan's Minister of Science and Education for his outstanding contribution to science.
